Abstract

L’invention concerne un capteur élastomère tubulaire (1) comprenant un élément tubulaire (10) en matériau polymère élastique présentant une cavité (12) s’étendant sur toute sa longueur, caractérisé en ce que :- l’élément tubulaire (10) est constitué sur toute sa longueur d’un premier matériau polymère conducteur électrique et d’un deuxième matériau polymère isolant électrique, le premier matériau polymère formant deux parties conductrices (14a, 14b) de l’élément tubulaire s’étendant au moins partiellement en regard l’une de l’autre, le deuxième matériau polymère formant deux parties électriquement isolantes (16a, 16b) s’étendant entre les deux parties conductrices afin de les isoler électriquement, - le premier matériau polymère présente une première dureté Shore A mesurée selon la norme ISO 48-4:2018, le deuxième matériau polymère présente une deuxième dureté Shore A mesurée selon la même norme, la deuxième dureté Shore A étant supérieure de la première dureté Shore A d’au moins 5 points.
